DISK WHEEL.

Specification of Letters Patent. I Patented J 11119 21, 1921,

Application filed November 7,1919. Serial No. 836,337.

which it appertains to make and use thesame, reference being had to theaccompanying drawings, and to figures of reference marked thereon, whichform part of this specification.

Like figures of reference refer to like parts.

This invention relates to disk wheels for vehicles.

One of the objects of this invention is to provide a disk wheel whereina single sheet of metal forms the wheel disk, which forms the functionof spokes, the felly of the wheel and part of the rim thereof.

Another object is to provide a sheet metal disk wheel havin sheet metalreinforcing parts about the hu which are of such shape as to easily lendthemselves to the processes of sheet metal stamping. And a furtherofject is to provide an auxiliary disk in connection with the main diskof the wheel, which auxiliary disk is provided with a peripheral recessadapting the peripheral edge of the auxiliary disk to abut against thesurface of the main disk, and also to have the recess contain someimpervious material which shall serve to exclude water from between themain disk and auxiliary disk.

The form of disk wheel which is the subject of this application, is animprovement on the one which is the object of my application filed Aug.23, 1919, under the Serial Number 319,396, and differs particularlytherefrom in the fact that in this invention of a disk wheel, part ofthe rim, the felly and the main disk are all incorporated in one sheetof metal.

' With these and other objects my invention consists in certain featuresof construction,

one embodiment of which is illustrated in the drawings, is hereinafterdescribed, its construction is explained, and what I claim is set forth.

In the drawings,

Figure 1 is a front plan view of a vehicle disk wheel embodying myinvention, having part of the wheel broken away to more fully illustrateits construction.

Fig. 2 is a section of the wheel shown in Fig. 1, taken on the line X Xthereof.

Fig. 3 is a perspective view of one of the bridging pieces used toreinforce the felly at the bolt connection of a rim part. L Fig. 4 is aplan of the auxiliary reinforcmgrdisk. I

ig. 5 is a, section taken on the line X--X of Fig. 4.

Fig. 6 is a plan of the backing plate.

Fig. 7 is a section taken on the line X-X of Fig.6.

Fig. 8 is a plan of the spacing and reinforcing rin'g.

Fig. 9 is a section taken on the line X--X of Fig. 8.

F ig. 10 is an enlarged section of the spacing thimble used between theauxiliary disk and the backing plate at the clamping studs.

Fig. 11 is an enlarged section of the flared portion of the felly andrim at the bolt hole.

Fig. 12 is a section of a modified form of rim to that shown in Figs. 1and 2.

In the figures, there is shown the usual form of axle 1, upon which thewheel is mounted, shown having a hub formation 2, of the Ford type, heldupon the axle 1, by the nut 3. The cap 4 in threaded engagement with thehub 2, covers the nut 3. Bolted to the flange 5, by the bolt 6 is abrake drum 7, which bolt 6, with five others firmly secures a hub bed'plate 8, to the flange 5. This bed plate 8, has an angular recess at 9,against which is fitted an auxiliary disk 10, having also a bearing at11, against the bed plate 8 near the hub 2. There. is a cylindricalportion at 12, having a bearing on the bed plate 8. This disk isstifi'ened by radial ribs 10*. At the periphery 10 of the disk 10 is anannular recess 10 filled with an impervious material 10 acting as a sealbetween the main and auxiliary disks to exclude water therebetween. Areinforcing plate 13, co-fitting the auxiliary disk 10, near the recess9, is provided. This reinforcing disk has a flange 14, which togetherwith the cylindrical portion 15, of the auxiliary disk 10, forms anabutment for the inner part of the main disk 16, which is forced incontact therewith, by means of the circular clamping plate 17, held inplace by the stud 18, with the nut 19. The stud 18 has a head 20,fitting into a recessed portion 21, of the bed plate 8. A stud 18 isprovided with a thimble 22, having a flange 23. Part of the thimble '22is partly in threaded engagement with the stud 18, and is screwed downtight, shouldering against the bed plate 8, to assist in holding thestud in place on the bed plate 8, and acts as a spacer between theauxiliary disk 10, and the bed plate 8, where the studs 18 pass throughto enga e the nut 19, and also to form a rigid backing to the gether bythe nut 19. There are three of these studs 18 equally spaced about thehub. The main disk 16 is shown in section to have an annular pocket 24on the front thereof, from which the metal diverges peripherally. Themetal is shown to extend peripherally beyond the pocket and to turn inthe opposite direction forming an annular pocket 25 on the rear side ofthe wheel, and in so doing, there is formed a felly for the wheel.

The metal continues peripherally until part 26 of the rim is formed.Coordinated with the part 26 of the rim is the rim ring part 27, whichis bolted to the felly 25, by means of bolts and nuts 28 and 29,respectively, the

heads 30 of which bolts pass through the body of a bridge iece 31, whichbridge piece 31, is electrically welded into place 1n the telly 25. Acotter pin 32 is provided to secure the head 30 from turning within thebridging piece 31. There is also provided a tube 33 incorporated in thefelly portion 25 In Figs. 1 and 2 is shown a clencher or inturned flangeform of rim, while in Fig. 12 the section shows the rim flanges 26 and27 flared outward.

It'will be noted that the principal part of the rim is shown as integralwith the an and main disk, and that the form herein shown in section,lends itself easily to the operations of stamping; Where the ring 27 isincorporated with t e shown, in enlarged section in Fig. 11, at theholes provided for the passage of the bolts 28, out-turned flanges 25",upon the telly ortion 25, which flanges 25 co-fit into the anges 27 onthe ring 27. The flanges 25 on the felly portion 25 do not project allthe way through the flanges 27, thereby rmitting the nut 29 to have afull bearmg upon the edge of the flange 27 only, in drawing the partstogether. These flanges 25' and 27?, interfittin'g as they do, relievethe bolts 28 of all transverse strain. Modifications of the oneembodiment of my invention herein shown, may be made without departingfrom the spirit and scope of the said invention. I therefore do not wishto be confined to this one embodiment.

Having described my invention, claim, 1. In a sheet metal disk wheelhaving a parts which are drawn to 'felly 25, there are fixed to saidflange, an auxiliary disk in shouldered engagement with said backingplate, a main disk spaced from said auxiliary disk at the contact of thelatter with said backing plate, and in fixed contact with said auxiliarydisk near its periphery, a reinforcing ring between said main saidauxiliary disk to strengthen the said wheel in abuttingrelation of theparts, a clamping plate concentrically positioned upon said hub, inbearing contact with said main disk, having a diameter suflicient tohave a direct bearing opposite said reinforcing ring and said auxiliarydisk, means holding said bearing and said backing plates in clampedrelation.
